We evaluate online sportsbooks based on the features that matter most during the NCAA Tournament. Here’s what we look at when determining the best March Madness betting sites:

📊 March Madness betting odds and lines

We compare moneylines, spreads, totals, and futures to ensure bettors are getting competitive pricing throughout the tournament. Strong March Madness betting odds provide better long-term value from the First Four through the national championship.

🎯 Bet variety and prop depth

Market depth is critical during March Madness. We assess the range of team props, alternative lines, live markets, and same-game parlays available across tournament matchups. Availability of player props varies by state due to regulations on betting on college athletes, which can impact overall betting options.

🎁 Bonuses and rollover terms

Welcome offers, tournament promotions, and fair wagering requirements all affect the value of betting on March Madness. We prioritize sportsbooks with competitive bonuses, clear terms, and realistic playthrough requirements.

📱 App performance

A reliable mobile app is essential during the fast-paced March Madness. We test navigation, loading speed, and overall responsiveness to ensure bettors can switch between games and place live wagers without friction.

🏦 Banking and withdrawals

We evaluate deposit and withdrawal methods for speed, security, and convenience. Transparent policies and multiple payment options help make managing your account simple throughout the tournament.

Trust matters. We focus on licensed U.S. betting sites with a track record of secure operations, strong customer support, and consistent user satisfaction.

By weighing these factors, we identify March Madness betting sites that combine value, reliability, and a smooth overall betting experience.

March Madness offers a fast-paced, high-stakes betting environment. With dozens of games across three weeks, there are plenty of ways to wager beyond simply picking winners. Here’s a breakdown of the main bet types to know:

Point spread

Instead of just picking a winner, point spreads let you wager on by how much a team will win or lose. Favorites need to exceed the spread, while underdogs can lose by less than the margin or win outright. Spreads are often bigger in the early rounds and tighten as matchups level out later in the tournament.

Example:

Duke -2.5 vs. Kentucky +2.5

Moneyline

Moneyline bets are the most straightforward: pick the team you think will win. In March Madness, unexpected upsets can make underdog moneylines especially rewarding.

Example:

Kansas -160 vs. UCLA +140

Totals (over/under)

Totals let you bet on the combined points scored in a game. College basketball can swing quickly, so totals offer a way to wager on scoring trends rather than team victory.

Example:

Gonzaga vs. Michigan Over 142.5, Under 142.5

Futures

Futures bets focus on tournament-wide outcomes, like which team will cut down the nets or who will make the Final Four. Odds fluctuate throughout the tournament based on performance and public betting, adding a strategic layer for long-term wagers.

Example:

Arizona to win the the National Championship +350

Parlays 

Parlays combine multiple bets into one ticket for a bigger potential payout, but every pick must hit. Same-game parlays take bets from a single matchup — spreads, totals, and team stats — and bundle them into one high-risk, high-reward wager. The best parlay betting sites make it easy to combine all your favorite wagers.

Prop bets

Prop bets focus on specific events or statistics rather than the final outcome of a game. For March Madness, this could include points, rebounds, assists, team milestones, or even the number of upsets in the tournament. Keep in mind that prop bet availability varies by state — particularly for individual player props — so you might not be able to utilize the best prop betting sites.

Teasers

Teasers are like a parlay with a cushion: they allow you to adjust spreads or totals in your favor across multiple games, which lowers the payout but gives extra margin for error — perfect for hedging multiple tournament bets.

Betting on March Madness is different from wagering on a single championship game. With 67 games played over three weeks, the NCAA Tournament rewards preparation, discipline, and a willingness to adapt as the bracket unfolds. Here are key strategy angles and tournament trends to consider.

📊 Expect volatility in early rounds

Upsets are part of March Madness history, but large spreads in the opening rounds don’t automatically mean easy underdog covers. Top seeds often dominate lower-seeded teams, yet double-digit seeds regularly keep games competitive. Pay close attention to tempo, 3-point shooting reliance, and turnover margins — those factors often determine whether big favorites cover.

🎯 Understand prop and market availability

Team props, alternative lines, and same-game parlays expand significantly during the tournament. However, player props on college athletes are not available in every state due to regulations. If betting on March Madness player markets is part of your strategy, confirm what’s offered in your jurisdiction before building your card.

📈 Monitor line movement throughout the week

March Madness features games nearly every day during peak rounds. Odds can shift quickly based on injury updates, sharp action, and public betting trends. Watching line movement — especially in standalone Sweet 16 and Elite Eight matchups — can help you find value before prices settle.

💰 Manage your bankroll across the bracket

With dozens of games on the board, it’s easy to overextend early in the tournament. Set a budget for the full three-week stretch and size your bets consistently. Saving room for later rounds can prevent chasing losses after a chaotic opening weekend.

🧠 Avoid betting with your bracket

It’s common to mix bracket loyalty with real-money wagers. Keep those separate. Betting on March Madness should be driven by matchup data and price value, not your Final Four picks or school allegiance.

March Madness betting apps are legal in more than 30 states and Washington, DC, but the rules aren’t identical across all jurisdictions. While all of the states below allow legal wagering on the NCAA Tournament, the availability of college player prop bets varies.

Some states prohibit player props entirely, while others allow them without restriction. Use the table below for a quick, side-by-side look at what’s permitted where you live.
